"Violet click beetle The violet click beetle (""Limoniscus violaceus"") is a black beetle, 12 mm long, with a faint blue/violet reflection. It gets its name from the family habit of springing upwards with an audible click if it falls on its back. The beetle is listed in Annex II of the EC Habitats Directive and Schedule 5 of the UK's Wildlife and Countryside Act 1981. It is also listed as Endangered in the GB Red List. It is to be found in only a few locations in Europe, including three sites in Britain. These are Windsor Forest (where it was"
"shorter. Larvae develop in hole of various host plants, mainly ash (""Fraxinus excelsior""), beech (""Fagus sylvatica"") and elm (""Ulmus"" spp.). The life cycle lasts 4–6 years. Pupation occurs in spring. These beetles are predatory. They especially prey on hermit beetle (""Osmoderma eremita"") and rose chafer (""Cetonia aurata""). When male ""E. ferrugineus"" are attracted to a female, they release compounds that attract other males to the site. These compounds include geranyl, nerylacetone and 6-methyl-5-heptene-2-one. Attraction of males only occurs in the presence of females, ensuring increased mating opportunities. Elater ferrugineus Elater ferrugineus, the rusty click beetle, is a species of click"
"and the whole pronotum is covered by fine puncture marks. The abdomen is brownish black, the wing covers reddish brown tinged with yellow, and the antennae and legs are pale reddish brown. The pronotum and wing covers are covered in dense, short greyish hairs. The larva is known as a wireworm and lives in the soil. It is yellow, slender, stiff and leathery, and grows to a length of about . The centre of the mandible has a small tooth for gnawing. The common click beetle is absent from the far north but is found in the rest of Europe,"
"has a dark spot on each side. The larvae reach a length of about . The elytra of newly emerged adults have a coating of a yellowish, waxy powder. As the beetle ages this powder wear off. The males apparently attract the females by a clicking sound produced by the elytra. This species usually mates in August. The larvae are miners of fallen timber, while adults are usually found walking around on the trunks of trees. Larva feed on decaying timber, especially of the Bombacaceae family (kapok or ceiba trees, mainly ""Ceiba pentandra "", ""Bombacopsis"" spp., ""Ochroma"" spp. and ""Pseudobombax"""

They feed on the leaves of grasses and also on pollen, and are often seen on the flower-heads of umbelliferous plants. The larvae are eaten by birds such as rooks, crows and starlings, particularly just after ploughing, and are also preyed on by insects such as ground beetles. They are also subject to attack by parasitic insects and bacterial and fungal pathogens.

The adults grow up to long and can mostly be encountered from May through July in broadleaved and coniferous host-trees. Denticollis linearis Denticollis linearis is a species of click beetle belonging to the family Elateridae subfamily Dendrometrinae. This beetle is present in most of Europe, in the East Palearctic ecozone, in the Nearctic ecozone and in the Near East. ""Denticollis linearis"" is quite similar to a Cantharidae species, but it can be distinguished from a soldier beetle by the two basal angles very protruding on pronotum and"

Their bioluminescence is similar to that of another group of beetles, the fireflies, although click beetles do not flash, but remain constantly glowing (though they can control the intensity; for example, they become brighter when touched by a potential predator). Also the larvae and the pupae have light organs and the eggs are luminous too. Adults feed on pollen, fermenting fruit and sometimes small insects, while the larvae live in the soil and feed on various plant materials and invertebrates, as well on the larvae of other beetles. This species can be found in Belize, Saint Vincent"

Click beetles emit an orange light from the abdomen when flying and a green light from the thorax when they are disturbed or moving about on the ground. The former is probably a sexual attractant but the latter may be defensive. Larvae of the click beetle ""Pyrophorus nyctophanus"" live in the surface layers of termite mounds in Brazil. They light up the mounds by emitting a bright greenish glow which attracts the flying insects on which they feed. In the marine environment,"

Once ""T. contractus"" has reached sexual maturity, the female produces a sex pheromone which attracts the male. Once the female has mated she no longer produces this pheromone, which suggests that she mates only once. There is no indication that this is true for the male. The odd beetle was given its other common name, the tissue paper beetle, because it was believed to eat tissue paper. It does not actually consume tissue"
